Crap Birder .
According to Roberts 1999 paper , on honey buzzards he has found birds usually
lay 10 days after nest construction , but on occasion are laying within 5 days and first eggs in nests from May 21st. With an incubation of 30 to 35 days ( depending on clutch size ) eggs could be hatching between June 20th and 25th , with 40 - 44 days for fledging July 29th - August 2nd and the young leaving the nest area August 12th-18th.
With the first sighting of our birds on the 16th of May , the female could have been sitting by May 25th and hatching could have occurred around June 25th and fledging in early August. So our first confirmed sighting of a juvenile was within the window Roberts suggests as being possible.
As for the 2014 sightings I only put sightings out when birds are seen in a wardened area to RBA and only if I see the birds myself or by a trusted watcher.
